獨角獸/ Nginx/Capistrano部署（服務器未啓動）

我一直在擊敗我的頭靠牆試圖弄清楚，我完全卡住了。我試圖部署一個處理域重定向的應用程序。它與我們的主Web應用程序一起運行，並具有一個將用戶從一個域重定向到另一個域的表。它是一個複雜的系統，但我不是最初的開發者，所以它有點落在我的腿上。它正在我們當前的生產服務器上運行，但我們正在轉向另一臺。我正在使用Capistrano將整個應用程序從我們的開發服務器移動到新的生產服務器。我們的應用程序的主要網絡端已被手動移動，似乎正常工作，但他們沒有複製這個網絡應用程序，當他們移動一切，所以現在我需要使用Capistrano來部署這個應用程序。獨角獸/ Nginx/Capistrano部署（服務器未啓動）

當我做一章部署生產，我收到此錯誤：如果我運行

unicorn

在應用

/電流麒麟服務器啓動了，但我必須去domain.com:8080讓它起作用並重定向...我真的不知道還有什麼可以做的，我確定它有些愚蠢，但我看不見它。我認爲，也許有一個問題與Nginx，但我什麼也沒有看到。

** [out :: 127.0.0.1] kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] ** [out :: 127.0.0.1] 看起來像kill命令不起作用。
